[Release] crewaiInc/crewAI 1.13.0: 1.13.0

CrewAI v1.13.0 introduces significant architectural improvements including RuntimeState RootModel for unified serialization, enhanced event telemetry for skills and memory, and A2UI extension support. The release includes critical bug fixes for GPT-5.x model compatibility, RBAC permission alignment, and Windows lancedb compatibility. Performance optimizations reduce framework overhead through lazy event bus implementation and conditional tracing.

Key Points

• •Implement RuntimeState RootModel for unified state serialization across the framework
• •Enhance event listener with new telemetry spans for skill and memory events to improve observability
• •Add A2UI extension with v0.8/v0.9 support including schemas and comprehensive documentation
• •Emit token usage data in LLMCallCompletedEvent for better cost tracking and monitoring
• •Fix GPT-5.x model compatibility by removing unsupported `stop` API parameter and adding to multimodal vision prefixes
• •Improve RBAC permission levels to accurately match UI options and add comprehensive permissions matrix
• •Reduce framework overhead with lazy event bus initialization and conditional tracing when disabled
• •Convert Flow and LLM classes to Pydantic BaseModel for improved type safety and validation
• •Cap lancedb below v0.30.1 to ensure Windows compatibility
• •Add comprehensive SSO configuration guide and agent-capabilities documentation across all languages
